Applications

integral visual leak testing of HEPA/ULPA filters

Standards

This system complies with or supports testing according to the following international standards:

(1) ISO 16890-2: Air filters for general ventilation – Part 2

(2) ISO 16890-3: Air filters for general ventilation – Part 3: Efficiency testing

(3) ISO 16890-4: Air filters for general ventilation – Part 4

(4) ASHRAE 52.2: Method of Testing General Ventilation Air-Cleaning Devices

(5) EN 779: Particulate air filters for general ventilation

(6) ISO 10121-3: Cleanroom air filter testing

Benefits

cost-effective solution for leak testing of filters ranging up to group H (filter class H13 and H14)

easy manual operation

constant test conditions due to pre-adjustable test parameters

effective testing of larger numbers with pre-adjusted test parameters

flexible and easily configurable filter holder for different filter dimensions

Principle

The filter element (sample) is mounted horizontally with the upstream side down on the test bench and secured with a pneumatically operated fixing device. For testing, the filter is then exposed to a flow of a polydisperse aerosol of oil droplets (DEHS).

An existing leak is made visible on a rising oil thread on the downstream side (upper side) of the filter.

Operation Instructions

System Setup: Mount filter horizontally in the pneumatic holder. Confirm compressed air and electrical supply.

Parameter Adjustment: Set aerosol flow and test duration according to filter size.

Test Execution: Apply DEHS aerosol to the upstream side. Observe downstream for rising oil threads indicating leaks.

Data Recording: Record visual inspection results manually; optionally photograph for documentation.

Safety: Ensure aerosol is contained, and personnel avoid direct contact.

Experimental Procedure

Preparation: Install filter and confirm all connections.

Testing: Start aerosol flow; monitor for visual leak indications.

Observation & Analysis: Inspect downstream side for oil threads; identify leak positions.

Reporting: Document results and store for quality control or production records.

Post-Test: Clean system, prepare for next sample.

Maintenance Information

Check pneumatic holder functionality and seals regularly.

Clean aerosol generator and bench after each test.

Replace DEHS supply and consumables as needed.

Inspect lighting and protective housing to maintain clear visibility.
